The Stereo Imager effect can change the width the the stereo image. It works with both stereo and mono input signals.
Stereo Imager window
The Width knob controls the stereo image width. The Reverse button reverses the left and right channels.
Mono input signals are converted to stereo using a filter. Two filter types are available:
- Shelve: Low frequencies are directed to the left channel, high frequencies are directed to the right channel. The Color knob controls the crossover-frequency.
- Comb: A delayed signal is added to the left channel and subtracted from the right channel. The Color knob controls the distance between the notches of this comb filter.
The Stereo Imager is mono compatible: if the stereo outputs are summed the resulting signal is equal to the original mono input signal.
